FREDERICK WILLIAM VICKERY, OF LONDON, ENGLAND.

PAPER PILING 0R LAYING MAGHINE.

To all whom t may concern Be it known that I, FREDERICK WILLIAM VICKERY, a subject of the King of Great Britain, residing at London, England, have invented certain new and useful Improvements in or Connected with Laying Machines, of which the following is a specification.

The object of this invention is to position the pressers of paper piling or laying machines next to the side gages, in order to press Vthe sheets down into the boxes orequivalents, and on to the pile, and thus enable the sheets to be keptstraight with their edges properly ,positioned between said gages, and in order, also, to actuate any suitable mechanism for regulating the raising and lowering of the delivery mechanism and its associated parts or the table or its equivalent.

The actuating mechanism just referred to does not require timing relative to the entrance of the sheet and this avoids the adjustment necessary in the ordinary machine in which consideration must be paid to the varying thicknesses of the paper being fed.

I will explain my invention as used in connection with my British prior Patents Nos. 17257/06, 21485/10, and 12143/11, although it is understood that I do not restrict myself to the particular actuating mechanism shown and described in those patents, nor to the construction shown and described in the present case, which is only an example of carrying my invention into practical effect for one particular use, and which will require to be modified without departing from the spirit of the invention when applied to various uses.

According to the present invention, vertically sliding presser members are provided at each side of the side gages shown in my said patents, and such members may be plain or have ratchet shaped teeth or grooves to engage the edges of the sheets upon beingl lowered to press the sheets into the boxes.

These members are raised by positive action and are allowed to lower by gravity, which method enables the lowering movement to be arrested as soon as the bottom of the member comes in contact with the top of the pile; the thickness of the said members is such as not to interfere with the passage of the sheet on to the pile, so that it is possible to move them up while the sheet is passing on to the pile until the' end has passed clear of the wedges Specification of Letters Patent.

Application filed December 8, 1913. Serial No. 805,420.

shown in said patents, when the next downward movement of the members forces the sheet on to the pile and has a tendency to iiatten the pile, and as the distance the members travel on their downward stroke regulates the raising and lowering mechanism, as hereafter described, it is an advantage to insure the piles being fiat. One or more members may be provided on each side of the side gage shown in British Patent No. 21485/10, and of course, any number of sets of members, according to the number of side gages being employed in the machine. The said members are preferably attached to the side gages so that when these side gages are moved, the members themselves are also moved at the same time, and are thus always kept in the same position relative to the side gages.

The invention is illustrated in the accompanying drawing.

Figure l is a side elevation of the machine showing the relative positions of the automatic mechanism, the presser appliance, the gage, and a pile of paper. Fig. 2 is a side elevation of one of the side gages, the presser appliance and its carrier. Fig. 3 is an end view of the pressers and gage. Fig. 4c is a fragmental plan view of the automatic mechanism here employed. Fig. 5 is an enlarged view of a detail.

l, l, are the pressers connected to arms 2, 2, suspended from one end of an arm 3, the other end of which is bent and pivoted to a stud 4C on the frame 5 which carries the side gage 6 and wedge or tapered block 7.

The outer sides of the pressers are formed with inclined, horizontal teeth 8, see Fig. 8, which extend the entire length thereof, and such pressers, when two are employed, are held at a distance apart so that they move simultaneously up and down the opposite sides of the gage plate 6, as it must be understood that when a number of cut sheets are being delivered side by side between the gages, pressers constructed in this way are employed with each gage except the outside gages, in which case there need be only one presser for each, such presser moving up and down on the side of the gage next to the paper.

In Figs. l and 2, a gage of special construction is shown as utilized for guiding the pressers 1, which are distanced also by blocks 8a, but such construction forms no part of the present invention.

Y thread ofthe rod 9 for effecting the raisingV 9 indicates threadedrrod, up and ldown which the conveyer belt roller, the automatic raising and lowering gear, pressers, gages, their carrier, and other appliances, are moved, las hereafter explained, all of these elements being carried'by a frame 10 which is slidably mounted on said rod, (one of such rods being on each side'of the machineas will be understood).

1n the frame V10 is journaled a shaft 11 which extends completely across the machine, andon thisr shaft there is provided for each rodi), a wcrm 12 gearing into a toothed wheel 13, the latter revolving` in a bracket 13a, on said frame and having a screw threaded axial opening embracing the screw and lowering of the frame andthe parts carried thereby.

l 1n each frame 10 is journaled a rock shaft 14,.which, like the shaft v pletely across the machine, and on this rock shaft are fixed levers 15 and 15EL located on opposite sides of the frame, the inner levers 15a carrying a rod 15b which also extends across the machine and which is connected to the Varms 3 -by links 16 on the end of the 'Y levers 15a. The lever 15 on the outside of the frame carries a roller 17 riding overa cam 18 projecting from a wheel 19 loosely7 mounted on the shaft 11.-V

n the shaft 11 is fixed one toothed member20 of a clutch, while the other toothed ing an extension 25a member 21 of the clutch is fixed to one face of the wheel 19, and on said face is also positioned a projecting cam piece 22, the other face of the wheel 19 having a projection 23 formed with a cam shaped edge 23?. On the face ofthe projection 23 is another projection 24 extending only over a portion of the projection 23 and having inclined ends 24a.

Secured to the frame is a socket 25 havwhich projects into the path of the cam 22, and such socket carries a rod 26., one end 27 of which is provided with a roller 28 whichy rides on theVV cam 23a.

A springk29 connected to the socket 25 and rod 26 normally tends to keep the roller 28 on the cam 23a, and the rod 26 is provided at the end opposite to the roller 28 with a notch 30 into which the nose 31 of arocking lever 32 pivoted to the lug33 on the frames 10 and 5 engages, as hereinafter explained.

34 is a spring connected to the frame 10 and the rocking lever 32 to normallyhold the nose 31 against a bar 35, which extends across the machine, and which, together with the shaft 11, when the latter is `engaged -by the aw 36 of the frame 5, will carry the said frame 5.and its appurtenances.

37 are guides on the gage carrier rod 38 to insure a truly vertical movement of the arm 3.

One end of the rocking lever 32 is 'pro- 11, extends ccm-l ed in the frame 10 and has securedto it a4 smaller wheel 42 meshing with the Vwheel 19, so'that the conveyer belt will transfer its motion, when required, to the shaftr 11 and wheel 13, as hereafter explained.

43 is the usual conveyer Abelt and 44 the roller for delivering the sheets of paper on to the pile 45. Y Y

' In action, each sheet is passed from the conveyer belt 43 over the wedges 7 where it is curled in a manner well known and passed by the roller 44 on to the pile 45. The motion of the vwheel 40 on the shaft Vof the conveying roller 41, which is driven from any desired part ,of the machine, is conveyed by the wheels 41a, 42, to the wheel V19,

the cam 18 of. which acts upon thelevers 15 and V15EL and moves the arm 3 and pressers 1 upward to a xed distance, while sucharm,

pressers, and levers are allowed to fall by their own'weight, the roller 17 following the cam, valsoto a fixed distance. vAt the same time, the roller 28 has been riding over the cam 23a, (or the projecting end 27 ofthe rod 26 has beenriding'against the face of the projecting piece 23), to move the rod 26 in one direction, such rod 'being held against the cam ,23a of the spring 29. Y Y

The vconstruction andl position withl rega-rd to 4each other .of the cam 22 and the inclined Iends 24EL are such that the wheel19 only clutches the shaft 11 at a portion of each revolution, said wheel being moved longitudinally in vone direction by the cam 22 engaging extension 25a; Yto unclutch the wheel 19 from the member 20, andafter the wheel 19 hastraveled a certain distance, Y

the projecting endY 27 of the rod 26 will ride "up one incline 24a, and force back the` on the -pille before they reach their full limit ofdownward movement and in consequence the machine runs correctly; but should the delivery of Vpaper not be in accordance with the movement of the mechanism, and should the pressers reach the full limit, or nearly'so,

cftheir downward movement before contactling with the pile, the rocking lever v32will be acted upon by the arm 3f The latter de- I Y presses the rollerk 39 `and-moves up the nose 31,` so that when the rod 26 has Yagain reached its highest movement, the nose .'31

engages the notch 30 of the rod 26 and holds it for a time, thus preventing the end 27 from having any action on the incline 24a during the next portion of its revolution, whereby the cam 22, having acted upon the extension 25a, will free the wheel 19 from the clutch, so that it will run free, and there will be no further movement of the raising gear until sufficient paper is fed on to the pile for the pile to offer suilicient resistance to prevent the full or nearlyfull lowering movement of the pressers 1.

The notch 30 and the nose 31 are undercut, so that once the arm 3 has forced the said nose into said notch and the cam has moved away from supporting the roller 28 although the arm 3 may be raised, the lever 32 cannot become disengaged, in order to allow rod 26 to go forward, until the cam again comes around and moves the rod 26 against the tension of the spring 29 through the medium roller 28; then lever 32 springs out and then only: that is to say, although there is no weight on roller 39, yet the action of the spring 29 pulling rod 26 against the nose 31, prevents lever 32 from releasing itself until the cam moves the rod 26 against the tension of spring 29.

What I do claim as my invention and desire to secure by Letters Patent is 1. In a machine for piling and laying sheets of paper, the combination, with a sheet-receiving element, and side gages associated therewith; of vertically-movable pressers disposed adjacent the opposite side faces of said gages and operative solely upon the edges of the pile of sheets on said element; and mechanism for raising said pressers, the pressers falling by the action of gravity.
